Glossary Forces: is a push or pull acting upon on object as a result of its interaction with another object.
Contact forces: Force that requires two pieces of matter to touch.
Friction: force of resistance to motion between two surfaces moving over each other.
Non- Contact Forces: Force that acts at a distance, three examples of non-contact forces are gravity, electric forces, and magnetic forces.
Gravity: is a force that holds things to the Earth´s surface and prevents things from floating off into the atmosphere.
Acceleration: rate at which velocity changes with time of both speed and direction.
Speed: is a measurement of how fast an object moves relative to a reference point. It does not have a direction and is considered a magnitude or scalar quantify.
Inertia: the resistence of any physical object to any change in its state or motion.
Machine: a tool that makes work easier.
Simple machine: basic machines that include the lever, wheel and axle, pulley, inclined plane, wedge and screw.
Lever: It is a type simple machine in which a bar moves around a fixed point or support called fulcrum.
Pulley. It is a simple machine consisting of a rope or cabel that runs around a grooved wheel.
Wheel And axle. It is a simple machine madre up of a circular object attached to a bar. This machine reduces the amount of force needed to do work.
Inclined plane: It is a simple machine that consists of a flat surface with one end higher than the other.
Wedge: It is a simple machine that can be made of one or two inclined planes. Some wedges, such as an axe, are made of two inclined planes placed back to back.
Screw: It is a simple machine consisting of a smooth cylinder with a tiny inclined plane wrapped around it.
Complex machine. It is a machine made up of two por more simple machines that make your work easier to do.
Structures. Are made up of several parts that support weight. The weight is distributed among the parts to make the structure strong and stable.
Mechanism: consist of two parts or more operating parts working together. For example, a bicycle transmission ir made up of a large gear and smaller gear joined by a chain.

Work: force is used yo moved a load.
